I looked into it again. Seems like you need to make an extra macro to enable gcode control.  
macro:  
[gcode\_macro M141]  
gcode:  
{% set s = params.S|default(0)|float %}  
SET\_TEMPERATURE\_FAN\_TARGET temperature\_fan=“exhaust\_fan” target={s}

I got it from [Chamber Temperature & Exhaust Fan | Voron Documentation](https://docs.vorondesign.com/community/howto/alchemyEngine/chamber_temperature_exhaust_fan.html) but had to change “chamber“ to “exhaust\_fan“

Now I can change the target via M141 s60 for example to set it at 60C
